Embedding a landing page in Craigslist

Craigslist doesn't support iFrame on their ads, which is necessary to embed an external site or landing page. 
Using Landing Pages from Craigslist Ads can still be a good way to generate leads and/or sales. Since Craigslist doesn't allow you to embed the landing page, you can advertise your product or service and then include a hyperlink such as: Order Here, Learn More, etc.
You can do this by inserting this HTML where you want the hyperlink. For example: 
Check out more product details here.<a href="http://yourlandingpage.com/">here</a> 
What the ad visitor will see:
Check out more product details here.
You can change up the hyperlink text to whatever description you'd like.
